At yesterday's BET Awards press conference, Chris Brown revealed that his next single, "They Don't Know," features unreleased Aaliyah vocals.

The video was shot this past weekend in Compton and also features the Crenshaw Colts Youth Football and Cheer teams.

Of the video, he said, "I shot it in the hood. I went to 60th Street and Cedar Block. [I'm] bringing both worlds together and trying to uplift the poverty side of the community and show them where I'm from. I'm from Virginia, but everybody comes from a broken home or being broke — I remember when I was."

Of the song, he said it will be on his X album along with tracks featuring Kendrick Lamar; Nicki Minaj; Pharrell; and long-time Aaliyah producer Timbaland, among others.

Though Breezy didn't mention any controversy in deciding to work with material from the singer, who was only 22 when she died tragically in 2001, one can't help but remember Drake's somewhat obsession with her (or the Drake-Chris-Rihanna drama).

The "Take Care" co-singer has Aaliyah's visage tatted on his back, and he's flipped her vocals numerous times in his music, most prominently on "Enough Said."

Brown's X is expected July 16.
